Accounting scandals typically involve executives misusing funds, overstating revenues or assets, or underreporting expenses or liabilities. This can amount to fraud. Common causes include executives temporarily reducing stock prices to facilitate company takeovers for personal gain or feeling pressured to alter financials for personal benefit. Some of the largest corporate accounting scandals include Enron inflating assets by $11 billion, WorldCom overstating assets by $3.8 billion, and Tyco executives stealing $150 million and inflating income by $500 million. These scandals often result in bankruptcy, large fines, and executive prison sentences.
